CHURN.

SPECIFICATION forming part of Letters Patent No. 787,655, dated April18, 1905. I

l Application filed August 25, 1904. Serial No. 222,198.

To all whom it mciy c'oncern:

Be it known that I, UHARLEY FREMONT AN- THONY, a citizen of the UnitedStates, residing.

at Ely, in the county of Linn and State of Iowa,

have in vented a new and useful Ohurn,of which the following is aspecification.

This invention relates to churns, and has for its object to simplify theconstruction and increase the efticiency of devices of this class.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designat ingcharacters, is illustrated the preferred form of the embodiment of theinvention capable of carrying the same into practical operation, itbeing understood that the invention is not necessarily limited thereto,as various changes in the shape, proportions, and general assemblage ofthe parts may be resorted to without departing from the principle of theinvention or sacrificing any of its advantages.

In the drawings thus employed, Figure l is a sectional side elevation.Fig. 2 is a transverse section on the line 2 2 of Fig. 1. Fig. 3 is atransverse section on the line 3 3 of Fig. 1. Fig. 4 is a side elevationwith the outer rim in section and the upper dasher member detached.

The cream-receptacle may be of any required size, form, or capacity andis supported upon a base 34 and provided with a cover 11, curvingdownwardly centrally and also at the outer edge, so that the cream whenmoved upwardly at the center will be deflected by contact with the coverand thrown down wardly again near the sides, as hereinafter explained.

Mounted for rotation within the receptacle 10 is a shaft 12, stepped byits lower end ina plate 13 on the bottom of the receptacle and supportedat the upper end above the receptacle by a bracket or standard 14,rising from the base 3 1, the standard having a detachable bushing 15 tocarry the shaft, so that the bearing may be quickly and cheaply renewedwhen worn or broken.

Attached to the shaft 12 rotatively near its lower end is a dashermember formed of a plurality of inclined radiating blades 16, preferablyconnected at the outer ends by an annular rim 17, the dasher connectedto the shaft, as by a set-screw 18 through its hub and bearing againstthe shaft.

Supported rotatively,as by acollar 19, Which is held rigidly upon theshaft 12 by a setscrew 20, is a sleeve 21, the sleeve loose upon theshaft and passing centrally through the cover member 11 and provided onits upper end outside the cover with a bevel-gear 22.

Attached to the sleeve 21, adjacent to the under side of the cover 11,is a dasher member formed of spaced annular rims 23 2 L,connected byspaced radiating inclined blades 25, the inner rim 23 spaced from thesleeve connected to the same by relatively small arms 26.

The shaft 12 is provided with a bevel-gear 27 upon its upper end, andengaging the two gears 22 27 is another bevel-gear, 28, upon a shaft 29,mounted for rotation in the standard 14, A pinion 30 is supported uponthe shaft 29 and engaged by a gear 31 on a stub-shaft 32, extending fromthe standard, the gear having an operating crank-handle 33. By thissimple means it is obvious that when the gear 31 is rotated in thedirection of the arrow in Fig.1 the shaft 12 and sleeve 21 will berotated in opposite directions and at accelerated speed caused by thedifference in size between the gear 31 and pinion 30. By this means itwill be noted that the cream in the receptacle will be drawn inwardlyand moved rapidly upward through the central open space in the upperdasher member by the action of the lower dasher member and impingedagainst the curved top 11 and thence carried outwardly and turneddownwardly and carried rapidly thence to the bottom of the casing againby the action of the inclined and reversely-revolving blades 25 of theupper dasher member. The

cream is thus caused to be constantly and rapidly moved upwardlycentrally of the receptacle and downwardly with equal celerity adjacentto the outer walls of the same, thereby rapidly and constantlycirculated and agitated, with the result of very quickly and thoroughlyseparating the butter particles from the cream.

The parts will preferably be of metal suit ably galvanized or otherwisecoated or protected and may be of any desired size or capacity.

Having thus described the invention, what is claimed is- 1. In achurn,the combination with a creamreceptacle, of a lower and an upperdasher member mounted for rotation in opposite directions within saidreceptacle; said lower dasher member comprisingahub and radiatinginclined blades for moving the contents of the receptacle in an inwardand upward direction; and said upper dasher member comprising concentricannular rims spaced from each other and from the axial supportingmember,

and inclined blades mounted between said rims for moving the contents ofthe receptacle in an outward and downward direction.

2. In achurn, the combination with acreamreceptacle, of a lower and anupper dasher member mounted for rotation in opposite directions upon avertical axis; the upper dasher member being of annular form and spacedfrom the axial supporting means; and the lower dasher member comprisinga hub and inclined blades for moving the contents of the receptacle inan upward direction through the eye of the upper dasher member.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.
